Finding the Player With the Most Kills(or any other variable)

I made a FPS shooter. The details aren’t important(I think). I am working on Different gamemodes to play(TDM, FFA, Objective) but I don’t know how I would get all the players score/kill variables and Figure out who has the highest score.
I don’t think it should be that hard but as I learned from the internet alone I do have some gaps in my UE4 knowledge


Not sure if you found a solution to this, but if anyone else comes across the same scenario, I will attach a proposed solution.
